Abstract

A self-cleaning joint is disclosed. The joint (15) is disposed in an air flow passage (30), such as that of a vacuum cleaner power nozzle (10), and allows an element attached thereto, such as a vacuum cleaner hose to which it is connected, to be pivoted between first and second positions. The joint (15) includes a chamber (20) and a tubular member (22) having a first portion (23) pivotably disposed in the chamber and a second portion (24) protrud­ ing from the chamber (20). To prevent abrasion of the joint (15) caused by the accumulation of abrasive particles, the inner walls of the chamber are provided with grooves (34, 35, 36) where any dust which penetrates the joint (15) can collect. The grooves (34, 35, 36) are positioned so that they are cleaned periodically by the flow of air in the passage (30).
